I'm a long time Digitech 2120 user so I'm familiar with the things you're looking for
On GSP if i want to switch a Effect on/off then i press Link on GSP, press the Btn on Footcotroller change the Value 1-127 or just on/off press link again and done.
So and if i want to assign Chorus & Delay to one Btn. just do it again on Delay and all is fine... that's pretty straight forward compared to MFC101!!!
There is a lot more that i can do on GSP but i can't do on AXE....
the Axe can assign multiple fx to a single single switch.. but it's not done the same way as with the GSP [which is seriously easy I know]
if you just want to turn things on and off you have a few possibilities..
scenes is an obvious choice.. and it's very easy to set up..
another possibility which is more flexible is to use modifiers [assign an IA to the MIDI CC that corresponds to the external modifier you want to use]
all this sounds complex but it's seriously not.. there's a pile of us in here that can walk you through it..
Unanswered Question:
1. How can i switch two or more Effects with one Btn on my MCF101 without using Scenes?
you can use modifiers..
personally, I like to use combinations of scenes and modifiers so I switch scene and trigger modifiers simultaneously..
this trick is immensely powerful..
can walk you through all this too
Most Important:
3. On my GSP if i switch from one Preset to the next one i could tell the Delay to stay until it's over... like i have a Lead Sound with heavy Delay on Preset2 and switch back to Preset 1 i could tell the GSP to keep the Delay until it's done... like 1 or 2 seconds... so that i could play the rhythm and the Delay fades out like normal...
there is no fx-unit out there that can handle "seamless" the way that the 2101 thru 2120 can when switching between presets..
not even the mighty Axe-II
there is an alternative though which works just as well..
you build more than one tone 'type' into your preset
for example.. you can build a preset that contains both your riffing tone and your soloing tone together..
here's a very simple example..
amp1 = JCM800 <-- riff
amp2 = 5150 mkI <--solo
you place the amps in parallel on the grid
imagine row2 on the grid is like this
in -> a few shunts -> amp1 -> cab1 -> many shunts -> delay -> reverb -> out
row3 is like this
the row2 shunt prior to amp1 also has a connection to row3: amp2 [the 5150] -> connects back up to row2 and goes into cab1
no matter if you use scenes or modifiers the following 'things' need to happen
IA switch in the off state = riff
amp1 = active [unbypassed]
amp2 = bypass: mute
reverb = bypass: mute fx in [so the reverb tail is not cut when bypassed but it now acts like a 'thru' for the dry signal]
delay = bypass: mute fx in [so the delay tail is not cut when bypassed but it now acts like a 'thru' for the dry signal]
IA switch in the on state = solo
amp1 = bypass: mute
amp2 =active [unbypassed]
reverb = active [unbypassed]
delay = active [unbypassed]
unlike the 2101, not all fx types have factory defaults.. only some do..
so you have to make your own or grab a sysex file from another user / axe-change
48K sample rate is set in stone..
if you don't like / want it, just do as you did with the 2101 and record what comes out of the 1/4" jack outputs..
